OBJECTIVE To compare the effects of low-calcium and high-calcium dialysate in stable ESRD patients on peritoneal dialysis (PD). METHODS Dialysate containing 2.5 mEq/l and 3.5 mEq/l calcium in combination with oral calcium salts as phosphate binders were evaluated. METHODS Tertiary-referral university hospital. METHODS Fifteen patients (6 male, 9 female) on low-calcium (2.5 mEq/l) and 15 patients (6 male, 9 female) on high-calcium (3.5 mEq/l) dialysate were studied for 6 months. All patients received calcium acetate or calcium carbonate to control hyperphosphatemia before the study. RESULTS Serum calcium, phosphorus and albumin did not differ before and after between the two groups. Three patients in low-calcium and five in high-calcium group developed hypercalcemia. Three in low-calcium group and four in high-calcium group required sucralfate to control hyperphosphatemia and hypercalcemia. Mean dose of elemental calcium was 1152 mg/day in low-calcium group and 790 mg/day in high-calcium group. A negative correlation (r = -0.82, p < 0.005) was observed between serum calcium and PTH at the end of study period in the low-calcium group. No such relationship was observed in the high-calcium group. CONCLUSIONS Degree and frequency of hypercalcemia appeared similar with low-calcium and high-calcium dialysate in peritoneal dialysis patients.

UI MeSH Term Description Entries
D007676 Kidney Failure, Chronic The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010281 Parathyroid Hormone A polypeptide hormone (84 amino acid residues) secreted by the PARATHYROID GLANDS which performs the essential role of maintaining intracellular CALCIUM levels in the body. Parathyroid hormone increases intracellular calcium by promoting the release of CALCIUM from BONE, increases the intestinal absorption of calcium, increases the renal tubular reabsorption of calcium, and increases the renal excretion of phosphates.

D010758 Phosphorus A non-metal element that has the atomic symbol P, atomic number 15, and atomic weight 31. It is an essential element that takes part in a broad variety of biochemical reactions.

D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
